UNITED STATE@ PATENT ROBERT L. LNDSTROM, OF TUSTIN, MICHIGAN.

SCREEN ATTACHMENT.

Application filed February 2S, 1914.

To all whom t may concern:

Be it known that I, ROBERT L. LINDSTROM, a citizen of the United States, residing at Tustin, in the county of Osceola and State of Michigan, have invented new and useful Improvements in Screen Attachments, of which the following is a specification.

This invention relates to screen attachments, and particularly to attachments for window screens., door screens or the like; and it has for its object the provision of a device of this character which will prevent insects, such as flies that customarily accumulate on one side of the screen and on the inside of the room to approach a portion of the screen where they will be compelled to pass to the outside.

`With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings Figure l is ay perspective view of one side of the screen; Fig. 2 is a perspective view of the opposite side thereof; and Fig. 3 is a vertical section through the screen.

The screen as herein contemplated may be used upon windows, doors or the like, and it is especially designed for the purpose of minimizing the possibility of flies or the like entering the roem from the outside and also causing such insects as may accumulate on the inner surface of the screen to travel to a point where they will be compelled naturally to escape to the outside. In view thereof use is made of a frame l consisting of the usual side bars 2, 2, a top bar 3 and a bottom bar e. To one side of the frame is arranged a sheet of foraminated material 4 such as the usual wire, and as shown this material is secured along its side edges, as at 5, to the side bars 2, 2, while at the lower edge the material is secured as at'6 to the bar 4. The upper edge of the material is embraced by a metallic deliector 7 which is located below the door 3 for a slight distance and arranged with relation thereto so as to define therewith an intervening exit passage approximately throughout the width of the frame. The said member 7 is disposed at an angle to the plane of the main body portion of the material and in view thereof it is evident that insects after escaping on the body of the screen to a point beneath the member 7 will on their Specification of Letters Patent.

final effort to ascend contact with the part 7 and thereby be defiected away from the opening between the part or member 7 and the mentioned adjacent edge of the bar 3.

At the back of the screen is an attachment consisting of a strip of material S secured at its sides to the side bars 2 of the frame and secured along its upper edge to the back of the bar 3. In this manner the material S is spaced from the foraminated material at the front of the screen. It will thus be seen that the flies or other insects that travel in an upward direction on the rear surface of the material it will finally pass into the space 9 between the materials e and S.

Secured to the lower edge of the material 8 is a guard l0, which is preferably formed of sheet metal, the lower edge of which is rolled over the lower edge of the material 8 and shown said guard is provided with an angular portion ll located in a plane below but substantially parallel with the plane of the deflected portion 7, which extends in the direction of the opening between the bar 3 and the member 7 The portion ll of the guard is provided with end flanges which bear against the inner surfaces of the bars 2, 2 and between its ends the said portion ll is provided with integral spacing extensions which extend over against the material 4. These extensions are provided with integral spurs l2 that are adapted to be extended between the material il and adapted to be upset thereagainst. The portien l0 of the guard ll thus serves to restrict the size of the passage 9 in an upward direction and to minimize the possibility of the flies from passing in a downward direction through the space between the material ai and the portion ll of the guard l0.

I claim z- In a screen attachment comprisinga frame with a sheet of foraininous material secured on one side thereof, an outturned deiiecting portion formed on said sheet at an angle to said frame and disposed to form a horizontal passage between the upper edge of said frame and the deflecting edge of said portion, a foraminous sheet on the opposite side of said frame extending below the top thereof with an inturned end extending nearly to the opposite foraminous sheet to form a passage therebetween said end being inclined in a plane below but substantially parallel with the plane of inclination of the said deectng portion, supporting mem- In testimony whereof I affix my sig-nature bers n spaced relation on said inclined end, n presence of two Witnesses. adapted to extend through the adjacent ROBERT L LINDSTROM oramnous sheet and fasten on the opposite 5 Side thereof slightly below the said out- Vtnesses:
